Abstract
The invention pertains to a vibration attenuating fluid coupling characterized by its ability to soundproof fluid conduit systems and permit limited misalignment between interconnected conduits without leakage. In particular, the structure of the invention may be utilized with existing couplings and fluid systems with minor modification. The coupling comprises a housing receiving the inner end of a nipple which supports a flange. An annular elastomeric ring within the housing imposes an axial force upon the nipple, and an inner bearing complimentary in configuration to existing housing surfaces and oriented therein by such surfaces is engaged by the nipple inner end and includes an elastomeric material wherein elastic material, alone, supports the nipple relative to the housing for absorbing vibrations and permitting misalignment.
